Sounds easy enough. One question though - wouldn't you now have a "security
invalid" message for all traces? Not that it matters for non-record/badge
work, but...

No, the GPS-NAV is designed such that you can replace the battery
without breaking the security seal. That is why power must be applied,
the contents of the security memory are then maintained by the external
power source. If no external power is connected when the battery is
removed, the contents of the security memory will be lost, and the
electronic seal will be broken.
